Q.3 For the following molecule, draw all stereoisomers and identify all pairs of enantiomers and diastereomers.
On b), I understand that we don't know which side of the molecule the Cl would attach on, but I was under the impression that we only show stereochemistry on a chiral center, and I do not see where the chiral center is on this molecule. Would you be able to explain this?
